It's been around 3 years since I grown and I've also only smoked a couple of times during this time. But now I sorta got hooked again 
I thought about it a long time and have had many plans until I decided to build this.
It's a dual chamber SCROG cabinet with chamber measuring 60x60x150cm (about 2x2x5 feet). That's the volume of the growing areas, the upper ventilation area is not included in these figures.
I built the cabinet inside a closet and its was hard to get any good photos because of the tight space but heres what I got:
First, a 3d image that shows the whole cabinet (impossible to photograph).
I built only 2 intakes per chamber instead of 4 which is quite enuff. This way the total intake area is 4 times the exhaust area.
The idea is to ventilate both chambers with just one fan. Air from both chambers is sucked into the upper left sound proofed box and further through the fan into the carbon filter and out through a hole in the roof. The space where the fan and filter is, is also sound proofed using the same 1 inch material. (see in pics below). So yes, I am pushing air through my filter, but it seems to work a charm!
Both the filter and fan are suspended using a rubber kind of bungee cord.
The fan is a systemair 125 m3/h. Have to wait and see if that's enuff power.
To the left is the "suction chamber" with a light trap (two 90 degree PVC elbows painted black inside). You can just about see the exhaust from the left chamber which will be for flowering using a 250W HPS.
Better view of the suction chamber. The insulation material is glued and stapled to the wooden frame.
The left chamber (bloom). B/W poly on the walls (not on door yet, that's on the still-to-do list). Same PVC light trap for air intake, works perfectly!
I will probaly mount a couple of computer fans above the intake to blow upwards throgh the scrog screen to help with air movement.
A shot from below looking up at the exhaust of the bloom chamber.
Here I installed the 250W MH in the right (veg) chamber to test the timer and check the temperature. Notice there is only one 90 degree PVC elbow here for each intake as I had to sacrifice two for the suction chamber. Didn't anticipate the light leek there at first. But 2 are enuff, there is absolutely no light leakage through the intakes.
With the 250W MH on for an hour and the fan running the temp was 75.6F (the 80.2 comes from a probe that was hanging just above the lamp).
That is about 24 degrees C.
Temps will rise when I add the 250W HPS but I will also seal the suction chamber completely for improved airflow.
Quite a mess on the roof at the moment, but you see the exhaust hole and the two ballasts and a fan that I'll probably use to "exhaust the exhaust air" out the closet into my apartment. I can leave the door open to the closet all day (and night) to improve air exhange and the fan will probably help getting the hot air quickly out of the closet.
There is a window that I light proofed but I'll probably need to keep it open during summer at least. Gotta remember to close it though before opening the cabinet
Still to do is seal the suction chamber, put b/w poly on the doors, build the scrog screens and germinate some seeds.
Oh, almost forgot... This will be a DWC setup with one plant in each chamber. The buckets are 4.5 gallon and I have some very nice and quiet Schego airpumps for them. First run from seed will be in soil though, to find a good female to take cuttings from and place in the bubblers.
The plan is to start filling the screen in the veg chamber under the MH light. When it's time to flower I just move the whole screen into the bloom chamber, take a few cuttings, place them in the veg chamber in a bubble cloner and when rooted, select the best looking clone and start filling a new screen. Time will tell how this will work out.
Nutes will be GH in the first soil run, then HESI hydro in the bubblers.
I'll be back with updates, hopefully soon.
